Best ResponseYou've already chosen the best response.1the xintercept means y = 0 so we can replace y with 0 in your equation to start with: \[ y2=\frac{1}{3} (x+3)^2 \\ 02=\frac{1}{3} (x+3)^2 \\ 2=\frac{1}{3} (x+3)^2\] I would multiply both sides by 3 to get \[ 3 \cdot 2=3 \cdot \frac{1}{3}\cdot (x+3)^2 \\ 6= (x+3)^2 \] or \[ (x+3)^2 = 6\] I would take the square root of both sides as the next step.
